LAST EDITED ON 08-19-11 AT 06:30 PM (EST)That's what I would have done as well, and I would also have stopped and made 20 u-turns, circled 20 streets twice each, stopped at a few out-of-the-way location multiple times each to completely throw them off. I would also have tossed the case as far as I could into the bushes, then checked to see if it was possible to see it at all from the path.
What killed the girls were two things - the blurting out of "after Banyan ... {deer in headlights look} ... wait, what's Banyan?" and the fact they hid the case only a short distance from the path where it could be seen or felt with the exploring stick.
I thought it was not bad of a concept for a show and would watch it again.
ETA: If they ever decided to bring this show up to Toronto and I got to take part, I know the perfect location to hide the case and I know where I'd go to create a false path to follow. Pick me, pick me!
